Abstract Testosterone has been associated with economically egoistic and materialistic behaviors, but -defensibly driven by reputable status seeking- also with economically fair, generous and cooperative behaviors. Problematically, social status and economic resources are inextricably intertwined in humans, thus testosterone’s primal motives are concealed. We critically addressed this issue by performing a placebo-controlled single-dose testosterone administration in young women, who played a game of bluff poker wherein concerns for status and resources collide. The profit-maximizing strategy in this game is to mislead the other players by bluffing randomly (independent of strength of the hand), thus also when holding very poor cards (cold bluffing). The profit-maximizing strategy also dictates the players in this poker game to never call the other players’ bluffs. For reputable-status seeking these materialistic strategies are disadvantageous; firstly, being caught cold bluffing damages one’s reputation by revealing deceptive intent and secondly, not calling the other players’ bluffs signals submission in blindly tolerating deception. Here we show that testosterone administration in this game of bluff poker significantly reduces random bluffing, as well as cold bluffing, while significantly increasing calling. Our data suggest that testosterone in humans primarily motivates for reputable-status seeking, even when this elicits behaviors that are economically disadvantageous.

Testosterone is associated with status-seeking behaviors such as competition, which may depend on whether one wins or loses status, but also on the stability of one’s status. We examined (1) to what extent testosterone administration affects competition behavior in repeated social contests in men with high or low rank, and (2), whether this relationship is moderated by hierarchy stability, as predicted by the status instability hypothesis. Using a real effort-based design in healthy male participants (N = 173 males), we first found that testosterone (vs. placebo) increased motivation to compete for status, but only in individuals with a low unstable status. A second part of the experiment, tailored to directly compare stable with unstable hierarchies, indicated that exogenous testosterone again increased competitive motivation in individuals with a low unstable status, but decreased competition behavior in men with low stable status. Additionally, exogenous testosterone increased motivation in those with a stable high status. Further analysis suggested that these effects were moderated by individuals’ trait dominance, and genetic differences assessed by the androgen receptor (CAG-repeat) and dopamine transporter (DAT1) polymorphisms. Our study provides evidence that testosterone specifically boosts status-related motivation when there is an opportunity to improve one’s social status. The findings contribute to our understanding of testosterone’s causal role in status-seeking motivation in competition behavior, and indicate that testosterone adaptively increases our drive for high status in a context-dependent manner. We discuss potential neurobiological pathways through which testosterone may attain these effects on behavior.

Testosterone has long been thought to increase risk-taking, but evidence supporting this association is mixed. Instead, testosterone’s key role may be to promote status-seeking behaviors. Here, we examined to what extent testosterone administration affects risk preferences for both monetary and social status outcomes, and whether this relationship is moderated by an individuals’ social status. Male participants (N=166) experienced high or low status in a competition task and then played two risk tasks; one involving gambles with only monetary outcomes, and another one involving gambles with non-monetary outcomes that influenced their social rank. We found that testosterone (vs. placebo) altered risk preferences for gains and losses in social rank, but not for monetary gains and losses. Specifically, testosterone increased risk-taking to increase social rank in individuals with high, but not low social status. These results demonstrate a context-dependent role of testosterone in regulating risk-taking for social status.

Background: The relationship between suicidal thinking and adolescent dating violence has not been previously explored in a sample of adolescent abortion patients. Aims: This paper highlights a study where the relationship between dating violence and severity of suicidal thinking was examined in a sample of 120 young women ages 14–21 seeking to terminate an unintended pregnancy. Methods: The Multidimensional Adolescent Assessment Scale and the Conflict in Adolescent Relationships Scale was used to gather information about psychosocial problems and dating violence so that the relationship between the two problems could be examined, while controlling for the other psychosocial problems. Results: The results suggest that dating violence was related to severity of suicidal thinking, and that the magnitude of this relationship was moderated by the severity of problems with aggression. Conclusions: Specifically, as the severity of participant’s general problems with aggression increased, the magnitude of the relationship between dating violence and severity of suicidal thinking increased. Limitations of the study and implications for practice are discussed.

ABSTRACT Ethinyloestradiol (EO) fed for various periods before mating to female hamsters affected the timing of mating and pregnancy rate. Slight effects on ovulation, foetal-crown rump length and resorption may have occurred, but effects on implantation were not apparent among pregnant hamsters. The response observed depended upon the feeding schedule adopted: hamsters fed 2.5 mg EO in a single dose, on day 3 before mating, mated normally but had a significantly lower pregnancy rate; on the other hand, animals fed 2.5 mg EO (0.21 mg/day) over three oestrous cycles, days 14–3 before mating, showed variations in the time of mating but had an essentially normal pregnancy rate; and, a group of hamsters who received the same total amount of EO (0.63 mg/day) over one oestrous cycle, days 6–3 premating, showed untowards effects by the steroid on both the timing of mating and pregnancy rate. The implications of these results are considered in relation to fertility control.

The present article focuses on one of the Greek delicacies mentioned by Photius and Eustathius, i.e. a Lydian import called kandaulos/kandylos. The dish was developed before the mid. VI th c. BC and named after a Lydian king, Kandaules, who ruled in the VII th c. BC. The delicacy was (via the Ionians) borrowed by the Helens and established itself in Greece sometime in the V th c. It became popular in Hellenistic times. The information we possess allow us to reconstruct two varieties of kandaulos/ kandylos. The first was savoury and consisted of cooked meat, stock, Phrygian cheese, breadcrumbs and dill (or fennel). The other included milk, lard, cheese and honey. The dish is reported to have been costly, prestigious and indicating the social status of those who would eat it. Though there is much evidence suggesting its popularity in antiquity, we lack solid evidence proving that kaunaudlos/kandylos was eaten in Byzantine times. On the other hand, Byzantine authors preserved the most detailed literary data on the delicacy. If it had not been for the Byzantine interest, our competence in the field of Greek cuisine would be even faultier.

This article contributes to the debate between the merits of the ‘politics of presence’ versus the ‘politics of ideas’ by examining the case of the first female Korean president, Park Geun-Hye. On the one hand, Park did not represent ‘the ideas’ of feminist politics. While her gender identity was widely propagated and accepted, it did not transform into deliberate identity-based politics. On the other hand, she contributed to the elevation of women’s social status through various unintended consequences, although Park’s ‘femininity without feminism’ inevitably led to the negligence of gender politics in her government. Indeed, Park’s existence, rather than her intention, stimulated the debate on the role and status of women in Korean society and enabled the rise of a number of first females in various sectors. In sum, the ‘politics of presence’ was triggered even without overt political measures.

Horace was writing hisEpodes1at the same time as he was writingSatires. The nameEpodesis derived from the metrical term ό ἐπῳδός (і.е. στίχος) which signifies the second and shorter line of a couplet, but Horace himself referred to them asiambi(soEpod. 14. 7,Epist. i. 19. 23). The collection is titledLiber Epodonin the MSS. and the title was used by grammarians of the fourth and fifth centuries. Butiambigives a better idea of their basic inspiration. Horace says of them(Epist. i. 19. 21-5):So he claims(a)originality,(b)Archilochus as a model,(c)that he was the first Roman to use Archilochus as a model, and(d)that he discarded the vicious personal invective of Archilochus. The judgement disregards Catullus, who had writteniambibefore Horace, but whose similarity to Archilochus did not extend far beyond metre and invective. There is a consistency in Horace’s poetic career: he began by recreating the poetry of Archilochus in hisEpodes, and his later—and greatest— work was the recreation in hisOdesof the lyric poetry of poets like Sappho, Alcaeus, and Pindar. There is a similarly close relationship between theSatiresand theEpistles;and, furthermore, all of his writing uses an autobiographical technique. There is another sort of consistency too, for basicallyEpodesandSatiresexpress a similar attitude of mind: anger, contempt, and amusement are the fundamental emotions (though he often transcends these emotions in both works), and a plausible case can be made out for regarding this as a sign of a young man of low social status, unsure of himself and his talent, and already finding ways of expressing a personality that were not too self-revealing. TheOdesandEpistles, on the other hand, express a more meditative, more philosophical, more humane attitude, yet ultimately no more self-revealing.

Cooperation in pairs of rats playing the prisoner's dilemma game was investigated. Six pairs of animals were taught to make either cooperative or uncooperative responses by running to one or the other end of a T-maze. Two T-mazes were joined together such that animals could respond simultaneously. Animals were run under conditions in which visual communication was present and absent. Mutually uncooperative responses were the most common and mutually cooperative behaviors the least preferred. Introduction of a barrier between the mazes, which removed visual communication between pairs, sharply accentuated uncooperative behavior. Similarities of the present findings to results with human subjects and the implications of using game theory for studying cooperative behavior in animals are discussed.

Tässä artikkelissa tarkastellaan, kuinka Suomen ja Unkarin pääministereitä puhutellaan Facebookissa. Tutkimuksen kohteena on se, mitä puhuttelukeinoja kommentoijat käyttävät kahdessa eri tarkoituksessa: toisaalta sympatian tai samaa mieltä olemisen, toisaalta erimielisyyden tai kritiikin ilmaisemisessa. Kahden sukukielen, suomen ja unkarin, puhuttelukeinot ovat samankaltaisia, mutta niiden käytössä on huomattavia eroja esimerkiksi sinuttelun ja teitittelyn yleisyydessä. Aineistona on viiteen Suomen pääministeri Juha Sipilän ja yhdeksään Unkarin pääministeri Viktor Orbánin vuosina 2015–2017 kirjoittamaan Facebook-päivitykseen tulleita kommentteja. Tarkastelun kohteena on 189 suomenkielistä ja 191 unkarinkielistä puhuttelumuotoa sisältävää kommenttia. Kommentit on jaettu myötäileviin ja vastustaviin ja näitä kahta kommenttityyppiä tarkastellaan kvantitatiivisesti ja kvalitatiivisesti pyrkimyksenä selvittää, mitä eroja puhuttelumuodon valinnassa ilmenee. Tutkimuksen teoreettis-metodisena taustana on aiempi sosiopragmaattinen puhuttelututkimus. Tutkimus osoittaa, että suomessa sinuttelu on hyvin yleistä riippumatta kommentin laadusta, mutta unkarissa sinuttelu on tavallisesti erimielisyyden osoittamisen keino. Tyypillinen kannustavan kommentin kirjoittaja käyttää suomessa sinuttelua ja pääministerin etunimeä, unkarissa teitittelyä, ön-teitittelypronominia ja pääministerin titteliä. Unkarin kielessä puhuteltavan yhteiskunnallinen asema vaikuttaakin puhuttelumuodon valintaan vahvemmin kuin suomessa. Toissijaisena strategiana unkarissa esiintyy jonkin verran myös uudenlaista kunnioittavaa sinuttelua yhdistettynä pääministerin etunimen käyttöön. Suomenkielisen aineiston vastustavissa kommenteissa esiintyy vielä todennäköisemmin sinuttelua kuin myötäilevissä kommenteissa sekä sinä-pronominia ja pääministerin sukunimeä, unkarinkielisessä aineistossa puolestaan sinuttelua, te ’sinä’ -pronominia ja pääministerin etu- tai sukunimeä tai nimenmuunnoksia. Toissijaisena strategiana joissain unkarin vastustavissa kommenteissa hyödynnetään ylikohteliaisuutta ja intentionaalista inkoherenssia. Aineiston perusteella näyttää siltä, että Facebook-kommenteissa käytetään suomessa etupäässä sinuttelua samoin kuin muissakin internetkeskusteluissa; kommentoijien mielipiteen ilmaisemisessa nominaalisilla puhuttelumuodoilla on tärkeä rooli. Unkarissa taas internetin yleisestä sinuttelupainotteisuudesta huolimatta tärkeimpänä keinona on sinuttelun ja teitittelyn vastakkainasettelu.   How to address a Prime Minister? Forms of address in comments to posts from the Prime Ministers of Finland and Hungary This article examines how the Prime Ministers of Finland and Hungary are addressed on Facebook. The aim of the study is to investigate which forms of address are used by commentators expressing, on the one hand, sympathy or consent, and on the other, disagreement or criticism. The repertoires of address forms of these two related languages, Finnish and Hungarian, bear many similarities, but the frequency and status of these forms are different. The data consists of comments on five posts written by Prime Minister of Finland Juha Sipilä and on nine posts written by Prime Minister of Hungary Viktor Orbán between 2015–2017, comprising a total of 189 comments in Finnish and 191 comments in Hungarian, all containing forms of address. The comments have been divided into two types: comments showing sympathy and comments showing disagreement or criticism. These two comment types have been analysed quantitatively and qualitatively aiming to determine how the address practices employed differ from each other. The theoretical background of this study is based upon previously conducted socio­pragmatic address research. The article shows that the use of T forms  is very common in Finnish, regardless of the type of comment, but that in Hungarian, T forms are typically used as a linguistic tool to express disagreement. In Finnish, a typical commentator showing sympathy will use T forms and address the Prime Minister by his first name, whereas in Hungarian V forms, the V form pronoun ön, and the title ‘Prime Minister’ are favoured. The social status of the addressee has a stronger effect on the choice of address forms in Hungarian than it does in Finnish. However, some Hungarian comments include a new, respectful type of T form used with the first name of the Prime Minister. In comments expressing disagreement in the Finnish data, writers favour T forms, especially T form pronouns, and the use of the Prime Minister’s surname, whereas in the Hungarian data T forms, the T form pronoun te ‘you’ and the use of the Prime Minister’s first name, surname or nicknames are the most typical address practices. In conclusion, commentators in the Finnish data seem to use mostly T forms on Facebook, thus imitating address practices common in other online conversations. Instead of the T/V opposition, nominal forms of address play an important role in expressing the commentators’ attitude. In the Hungarian data, despite the prevalence of the T forms in online chats, the most important resource in expressing relation to the Prime Minister seems to be the contrast between the T and V forms, reflecting their significant status in Hungarian.
