Forty litters of eight pigs each were paired by age and weight and re-grouped at the beginning of a 12-wk grower/finisher period. Each pair of litters was assigned to two pens, with two pigs from one litter (Minority) and six pigs from the other (Majority) in each pen. Four pairs of litters were removed from the experiment due to loss of pigs from injury or poor health. Agonistic encounters following re-grouping were used to rank each Minority pig and to classify it as being within the Dominant or Subordinate half of the social hierarchy. Minority pigs within a pen tended to obtain similar social ranks (within two ranks in 20 of 30 pens; P < 0.05), but were as likely to be Dominant as Subordinate (11 vs. 9 pairs, respectively). The activity and position of all pigs were sampled once daily, 5 days a week. One Minority pig was designated as the focal pig for these observations. The second Minority pig was more likely to be engaged in the same activity as the focal pig than were Majority pigs (P < 0.01), and would lie closer to the focal pig than would the Majority pigs (P < 0.01). There were no differences in the proportion of Majority and Minority pigs which were removed from the experiment due to injuries, nor in the type of injuries requiring their removal. Examination of all pigs at the mid-point of the study revealed some evidence of injury on the head, ears, shoulders, back, flanks, ramp and tail of 76, 75, 87, 90, 91 and 95% of the pigs, respectively, but no differences between Majority and Minority pigs in location or severity of injuries. Average daily gain for the entire experiment was 775 g d−1, and did not differ between Majority and Minority pigs during any 2-wk period of the study. It is concluded that littermates continue to associate with each other after re-grouping and that they attain similar social status. However, the litter with the largest number of pigs present does not consistently achieve social dominance or a competitive advantage manifested in improved weight gain. Key words: Pigs, littermates, re-grouping, social status

Why would people conform more to others with higher social positions? People may place higher confidence in the opinions of those who rank higher in the social hierarchy, or they may wish to make better impressions on people of higher social status. We investigated how individual preferences for novel stimuli are influenced by the preferences of others in the social hierarchy and whether anonymity affects such preference changes. After manipulation of their social rank, participants were asked to indicate how much they liked or disliked a series of images. Then, they were shown the rating given to each image by a partner (either inferior or superior in social rank) and were given a chance to adjust their ratings. The participants were more likely to change their preferences to match those of a superior partner in the public vs. private condition. The tendency to conform to the views of the superior partner was stronger among those with higher social dominance orientation (SDO) and those with greater fear of negative evaluation (FNE) by others. Altogether, the findings suggest that the motivation to make better impressions on people of higher social status can be the major driver of conformity to others with higher social positions.

One hundred and twenty-eight gilts were used to evaluate the effect of reducing the level of feeding at estrus on conception rate and embryonic survival. Within each of 4 yr, 16 Yorkshire and 16 Lacombe gilts were penned individually in a piggery, fed 2 kg of diet once daily and 11 days after being observed in estrus were fed 2.5 kg of diet (H). The gilts were mated on the first (day 0) and second day of estrus with two boars of the other breed. On day 1 feed intake was reduced to 1.5 kg (L) per day for one-half of the gilts of each breed. On day 11 the feeding level was switched for one-half of the gilts in each of the two groups to give four feeding level treatments of HH, HL, LH and LL. All gilts were slaughtered between days 30 and 35. The breeds did not differ in average daily gain (ADG), conception rate, or embryonic survival. The Yorkshire gilts had fewer (P < 0.01) corpora lutea (12.0 vs. 13.1) and fetuses (9.3 vs. 11.1) than the Lacombe gilts. The HH and LH gilts had higher ADG than HL and LL gilts (P < 0.01). The HH, HL and LH gilts had higher (P < 0.01) conception rates than the LL gilts (87.1, 86.2 and 87.1% vs. 64.3%, respectively). The numbers of corpora lutea and fetuses were not significantly different among treatments. However, when the H and L treatments to day 10 were compared, the L gilts had more fetuses (11.0 vs. 9.5) and a higher embryonic survival (86.2 vs. 75.8%) than the H gilts (P < 0.05). A body weight maintenance feeding level for 10 days after mating appeared to improve embryonic survival. Key words: Gilts, feed restriction, conception rate, embryonic survival

Abstract Survival, feed efficiency, growth, and fertility of swine are dependent on colostrum intake in the first 24 h after birth. This study determined the effects of three doses of a homogeneous colostrum sample on 24-h body weight, rectal temperature (RT), immunocrit, and growth and survival to postnatal day (PND) 7. Three female piglets were selected from eight litters (n = 24 piglets) at birth, removed from their litter, and bottle-fed 10% (COL10, n = 8), 15% (COL15, n = 8), or 20% (COL20, n = 8) colostrum based on birth weight over 12 bottle feedings every 2 h. At 24 h, piglets were weighed, RT recorded, and blood was collected to measure immunocrit. Piglets were returned to the litter of origin, and weight was measured daily until PND 7. Colostrum dose had an overall effect on weight gain at 24 h, RT, immunocrit, and growth to PND 7 (P &lt; 0.05). Piglets in the 20% BrW colostrum group had greater weight gain, RT, and immunocrit at 24 h than COL10 piglets (P &lt; 0.05), but these variables were not different between COL15 and the other treatments. Despite no difference in average daily gain after being returned to their litters, the greater weight (P &lt; 0.05) in COL20 compared to COL10 and COL15 was sustained over 7 d. Seven piglets in each treatment survived to PND 7. This model using standardized doses of a homogeneous colostrum sample enables controlled studies aimed at understanding the role of 24-h colostrum intake on piglet development.

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.

Abstract Annual ryegrass (Lolium multiflorum Lam.) can be divided into two cytotypes: diploid (2n = 2x) and tetraploid (2n = 4x). Polyploid versions of a given plant species result in increased seedling vigor, more robust growth and, potentially, greater yield. While most data suggest no difference in yield between diploid and tetraploid cultivars, there is still potential for weight gain advantages thanks to increased non-structural carbohydrates in tetraploid cells. The objectives of this study were to compare weight gain of cattle grazing either diploid or tetraploid cultivars of annual ryegrass. Two diploid annual ryegrass cultivars (Marshall and Tam 90) and two tetraploid cultivars (Jumbo and Nelson) were planted in 0.81-ha pastures, each replicated four times. Four steers (mean initial BW = 214 kg) were randomly assigned to each pasture for an 82-d grazing period. Body weights were recorded starting at d0 then every 28 days throughout the season. Data were analyzed in the GLM procedure of SAS using a significance level of α = 0.05. There were significant differences between cytotypes with respect to seasonal yield with diploids (9547.90 kg/ha) yielding greater than tetraploids (7762.00 kg/ha). As expected, ADF and NDF fractions were significantly less for tetraploids (ADF; 31.39%, NDF; 31.39%) compared to diploids (ADF; 33.75%, NDF; 53.25%). Tetraploids also contained significantly greater crude protein (13.50%) than diploids (12.90%). Cytotype had no effect on final average daily gain (ADG) (P = 0.9427). However, final ADG was significantly impacted by cultivar (P = 0.0134). Final ADG for Tam 90 (1.10 kg/d) was greater than Marshall (0.92 kg/d). Cattle grazing Nelson (1.04 kg/d) and Jumbo (0.99 kg/d) did not differ. Results show that regardless of differences in seasonal yield and nutritive value between cytotypes, there were no advantages in ADG for cattle grazing either cytotype.

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.

Sex differences and social context independently contribute to the development of stress-related disorders. However, less is known about how their interplay might influence behavior and physiology. Here we focused on social hierarchy status, a major component of the social environment in mice, and whether it influences behavioral adaptation to chronic stress in a sex-specific manner. We used a high-throughput automated behavioral monitoring system to assess social dominance in same-sex, group-living mice. We found that position in the social hierarchy at baseline was a significant predictor of multiple behavioral outcomes following exposure to chronic stress. Crucially, this association carried opposite consequences for the two sexes. This work demonstrates the importance of recognizing the interplay between sex and social factors and enhances our understating of how individual differences shape the stress response.

The combined effect of homobiotics, probiotics based on recombinant strains of g. Bacillus, & enrofloxacin on the dynamics of body weight gain in geese was studied. According to the principle of steam-analogs, one control and five experimental groups of 10 goslings in each group were formed. Gosyatam experimental groups used homobiotics vetom 15.1; vetom 13.1 incombination with enrofloxacin followed by replacement with a probiotic preparation Vetom 1.2. The absolute body weight and average daily gain in geese under the influence of the studied drugs increases. The severity of the effect depended on the pharmacological composition of the drugs used. The maximum absolute weight gain was observed when using the drugs according to the scheme: vetom 13.1 at doses of 25–50 mg/kg for 16 days, with further use of a 10% enrofloxacin solution at a dose of 0.5 ml/kg for 5 days and in The experiment period was 1.2 at a dose of 50 mg/kg for 16 days. After the cessation of the use of drugs, the growth rate increased for 30 days when prescribing the drugs according to the scheme: veto 13.1 at a dose of 50 mg/kg for 16 days and with further introduction of homobiotic veto 1.2 into the bird in a dose of 50 mg/kg for 16 days. The maximum average daily gain in live weight of geese was observed in the period from the 16th to the 32nd day with the administration scheme: homobiotic vetom 13.1 at a dose of 25 mg/kg of body weight 1 time per day for 5 consecutive days, then every other day for 16 days, then daily 10 % solution of enrofloxacin at a dose of 0.5 ml/kg of body weight for 5 days, then vetom 1.2 at a dose of 25 mg/kg once a day for 16 days in a row. And the maximum average daily gain in the post using period of the drug was observed on the 32nd day of the study according to the scheme: homobiotic veto 15.1 at a dose of 50 mg/kg of body weight 1 time per day for 16 days, then daily with vetom 1.2 at the same dose 1 once a day for 16 days. The studied drugs in the applied doses did not have a toxic effect on the physiological state of geese.

Families were fundamental to social hierarchy in early modern France. Birth was widely accepted to indicate one’s divinely ordained social status, even if that view was not universal—in practice, some freedom was allowed for individuals to improve their status (especially among certain social groups) or indeed to worsen it. Certainly, the relation of birth to social status varied. It had a changing history even in respect of the nobility, which could be entered by routes other than birth. But birth was primordial at all levels of society, and for the nobility it became even more so in France in the second half of the sixteenth century and in the seventeenth. It was widely believed that the members of a given noble family shared their own, generally superior, instantiation of human nature. On the other hand, heredity was widely believed to predispose commoners too in certain directions.

Abstract This study aimed to visualise the written versions of legends, which can transform the intangible culture as one of the significant parts of culture covering human facts and some habits like art, customs, traditions, into the tangible culture which is the other part of culture, through certain theme/s. Within this perspective, the study aimed to transform the women and discursive representation styles given in the Turkish Cypriot legends into visual representation in addition to creating an absolute language through the use of homogenous indicators. The study discussed the woman described with the ‘passive’, ‘oppressed’, ‘victim’ and ‘sinful’ features, in brief her marginalisation with the patriarchal legend structure through the use of semiotics. For the visualisation of legends, regardless the positive or negative consequence of woman, the ‘torn paper - collage with its popular name - texture was used to create a common language and the emotions to be reflected were symbolised with various colours. The content references of colours were taken into account; for instance, purple was used in the images that woman was downtrodden and blue in the images with the dominant male hegemony. Since the themes covered generally referred to the ‘mother nature’, the woman figures were illustrated as naked delivering the woman in her purest, simplest and most natural self without the social status indicators symbolised by the clothes. The main scene and woman figures, mountain and sea motifs in the selected legends were re-fictionalised in the digital environment and finalised with the illustration. As the effectiveness of pictorial elements in teaching and facilitating to remember the legends, as a cultural element within the main scope of this study is known, the legends were illustrated through the digital collage method. Therefore, the contribution was aimed to be reflected on the permanence and popularity of legends as a cultural product and verbal asset with the benefits of visual and artistic language.
