Many experiments have tested the foraging behaviours of birds relative to their social status. However, results are still not completely clear about the relationship between foraging behaviour and social status in birds. Some studies have shown that dominants use subordinates as food finders, while others show the opposite. Whether dominants search by themselves or wait to exploit the findings of a subordinate is still an unanswered question. For testing these alternative hypotheses, we carried out a laboratory experiment that used female common domesticated canaries, Serinus canaria (L., 1758). We used strict female flocks to avoid any bias based on pair bonds. We looked at the foraging behaviours of females relative to their social status using a foraging board. Our results showed that dominant females behaved as their own food finder. They began searching in the first position and had greater re-search behaviours, which allowed them to find seeds more rapidly than subordinates. Our study showed that foraging behaviour of dominants may be independent of the activities of subordinates. Our results also showed that there was no difference between the number of attacks received by dominants and subordinates when they were on the foraging board, which suggests that subordinates accessed the foraging board less frequently to avoid competition with dominants. We also suggest that environmental conditions may be one explanation for the differences observed among the different studies.

Research has shown that perceived group status positively predicts competence stereotypes but does not positively predict warmth stereotypes. The present study identified circumstances in which group status positively predicts both warmth and competence judgments. Students (N = 86) rated one of two groups (psychologists vs. engineers) presented as either being low or high in social status on warmth and competence. Results showed that status positively predicted competence stereotypes for both groups, but warmth stereotypes only for psychologists, for whom warmth traits are perceived to be functional in goal achievement. Moreover, for psychologists perceived warmth mediated the relationship between status and perceived competence. Results are discussed in terms of the contextual malleability of the relationship between perceived status, warmth, and competence.

Abstrak Kata Kunci: Pragamtik, Tindak Tutur, Implikatur, Kisah Sayyidah Maryam   Kisah Sayyidah Maryam dalam al-Qur’a>n merupakan salah-satu kisah yang menarik dikaji dengan pendekatan pragmatik. Hal ini disebabkan, secara tekstual, beliau adalah publik figur yang fenomenal, bahkan mengalahkan status sosial perempuan lainnya, sehingga namanya terdokumentasikan dalam satu surat khusus yang populer dengan sebutan ”Surat Maryam”. Kecuali itu, kisah tersebut juga termasuk kisah yang kaya dengan nuansa konteks. Sementara posisi ilmu prgamatik sendiri  merupakan disiplin keilmuan yang mengkaji satuan bahasa dari sudut pandang relasi antara konteks linguistik yang bersifat diadik dan konteks non-linguistik yang bersifat triadik. Penelitian ini hendak mengungkap dua hal; Pertama, apa yang dimaksud pragmatika al-Qur’a>n?. Kedua, bagaimana bentuk aplikasi pragmatik tindak tutur dan implikatur terhadap fragmentasi kisah kelahiran Sayyidah Maryam dalam al-Qur’an?. Tujuan kedua pertanyaan tersebut untuk memahami konsep prgamtika al-Qur’an, juga untuk mengungkap bentuk tindak tutur dan implikatur fragmentasi kisah kelahiran Sayyidah Maryam. Penelitian ini menghasilkan kesimpulan; Pertama, pragmatika al-Qur’an adalah suatu disiplin ilmu yang mengkaji al-Qur’a>n dari sudut pandang relasi antara konteks kebahasaan dengan konteks non-kebahasaan. Kedua, tindak tutur fragmentasi kisah kelahiran Sayyidah Maryam yang terdapat dalam Qs. A<li ‘Imra>n (03): 36, lokusinya berupa kalimat informatif, sementara illokusinya merupakan bentuk kalimat asertif yang bermakna mengeluh. Adapun implikaturnya sebagai pelajaran, bahwa jika segala sesuatu telah dipasrahkan sama Allah swt. maka tidak pantas mencari kesalahan atas peraturan yang telah ditetapkan-Nya.               Abstract Keywords: Pragamtik, Speech Acts, implicatures, Story of Sayyidah Maryam   The story of Sayyidah Maryam in the al-Qur'a>n is one-on-one interesting stories studied with a pragmatic approach. This is due, textually, he is a public figure who is phenomenal, even beating out other women's social status, so the name is documented in a special letter that is popularly known as "Surah Maryam". Except that, the story also included a story rich with nuances of context. While the position pragamatic science itself is a scientific discipline that examines unit of language from the perspective of the relationship between linguistic context that is both dyadic and non-linguistic context that is triadic. This research seeks to reveal two things; First, what is meant pragmatic al-Qur'a>n?. Second, how the application form pragmatics of speech acts and implicatures to fragmentation birth story of Sayyidah Maryam in the al-Qur'a>n?. The second purpose of these questions to understand the concept pragamtic al-Qur'a>n, as well as to reveal the shape of speech acts and implicatures fragmentation of the birth story of Sayyidah Maryam. This research resulted in the conclusion; First, the pragmatics of the al-Qur’a>n is a discipline that examines al-Qur'a>n from the viewpoint of the relationship between linguistic context with non-linguistic context. Second, the speech act fragmentation birth story of Sayyidah Maryam contained in Qs. A<li 'Imra>n (03): 36, locutionary acts be informative sentence, while illocutionary acts an assertive form meaningful sentences complaining. The implicature as a lesson, that if everything was handled the same God, it is inappropriate to find fault with the regulations set his.

Abstract Background The United Nations Convention on the Rights of Persons with Disabilities [1] highlights the need to create proper socioeconomic and political conditions for persons with disabilities, with a special focus on their immediate living conditions. According to the Convention, these conditions should be built to ensure that persons with disabilities have the potential to enjoy a high quality of life (QoL), and this principle is reflected in the notion of livable areas. The crucial aspect of this framework is the relationship between the individual QoL and the environment, broadly understood as the socioeconomic as well as the technical conditions in which persons with disabilities function. Methods The basic research problem was to assess the relationship between individual QoL for the population with disabilities as a dependent variable and livability indicators as independent variables, controlling for individual characteristics. The study used a dataset from the EU-SILC (European Union Statistics on Income and Living Conditions) survey carried out in 2015 in Poland. The research concept involved several steps. First, we created a variable measuring the QoL for the entire population with disabilities. To measure the multidimensional QoL, we used Sen’s capability approach as a general concept, which was operationalized by the MIMIC (multiple indicators multiple causes) model. In the second step, we identified the livability indicators available in the official statistics, and merged them with survey data. Finally, in the last step, we ran the regression analysis. We also checked the data for the nested structure. Results We confirmed that the general environmental conditions, focused on creating livable areas, played a significant role in shaping the QoL of persons with disabilities; i.e., we found that the higher the level of the local Human Development Index, the higher the quality of life of the individuals living in this area. This relationship held even after controlling for the demographic characteristics of the respondents. Moreover, we found that in addition to the general environmental conditions, the conditions created especially for persons with disabilities (i.e., services for this group and support for their living conditions) affected the QoL of these individuals. Conclusions The results illustrate the need to strengthen policies aimed at promoting the QoL of persons with disabilities by creating access to community assets and services that can contribute to improving the life chances of this population.

Bullying bystander behavior has an important effect on bullying—both in stopping and facilitating it. Although bullying bystander behaviors have long been understood as a peer group process, existing research that focuses on the role of peer factors is still limited. Moreover, less is known about the social cognitive-related role of peer factors and its underlying mechanisms in adolescents’ bullying bystander behaviors. Accordingly, using resource control theory, this study examines the mediating effects of popularity goals on the associations between social status insecurity and bullying bystander behaviors (active defending behaviors, passive bystanding behaviors) among 333 Chinese adolescents (181 males; Mage = 13.10; SD = .50). Analyses were conducted using SPSS 23 to conduct descriptive and correlation analyses. The hypothesized mediation model was tested using a structural equation modeling approach with bootstrapping techniques (bootstrap replications: 5,000) using AMOS 23. The results showed that popularity goals fully mediated the relationship between adolescents’ social status insecurity and their active defending behaviors. No gender differences in these mediating effects were observed. The results also indicated that popularity goals did not mediate the relationship between social status insecurity and passive bystanding behaviors. These findings enrich our understanding of bullying bystander behaviors and highlight the positive role of social cognitive factors (e.g., popularity goals) in active defending behaviors. Our findings deepen our understanding of bullying bystanders through integrating proximate and ultimate approaches. Our findings have significant practical implications, which suggest that school anti-bullying interventions should value the positive roles of social status insecurity and popularity goals in promoting active defending behaviors.

The relationship between cognitive impulsivity, as measured by Kagan's Matching Familiar Figures Test (MFF), and interpersonal popularity was investigated in a sample of 42 “predelinquent” preadolescent boys in a residential setting. Predictions that the relationship would vary with the specific sociometric situations sampled were generally not confirmed. In fact, both the latency and errors dimensions of the MFF proved to have comparatively little association with social status, with age and intelligence demonstrating much stronger correlations with sociometric scores. Similarities to, and differences from, results with nondelinquent populations are discussed, as are implications for attempts at modifying cognitive style.

It has been shown that adults of Glossina morsitans Westw. that have fed from a bait ox in their natural environment digest their blood meals more rapidly than others that have emerged and been fed in the laboratory, even when both are maintained under identical environmental conditions after feeding.In further experiments with G. morsitans in Rhodesia, flies caught in the field and fed in the laboratory were found to lose their ability to digest their meals rapidly. Measurements, made throughout three hunger cycles, of the rate of digestion, as reflected in the rate of excretion, of blood meals by field-caught flies fed on guineapigs in the laboratory showed that this was not significantly different from that of the normal, flied-fed flies during the first two hunger cycles but that during the third it fell to a level comparable to that of flise that emerged and were fed in the laboratory.It is concluded that whatever may be the events that condition the field flies to digest their meals rapidly in the natural environment, these are repeated with the ingestion of each meal, and that laboratory conditions cause a rapid loss of this greater digestive capability.
