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.

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.

AbstractGibberellin (GA), auxin (IAA) and brassinosteroid (BR) are indispensable in the process of plant growth and development. Currently, research on the regulatory mechanism of phytohormones in banana dwarfism is mainly focused on GA, and few studies are focused on IAA and BR. In this study, we measured the contents of endogenous GA, IAA and BR and compared the transcriptomes of wild-type Williams banana and its dwarf mutant across five successive growth periods. We investigated the relationship between hormones and banana dwarfism and explored differential gene expression through transcriptome analysis, thus revealing the possible metabolic regulatory mechanism. We inferred a complex regulatory network of banana dwarfing. In terms of endogenous hormone levels, GA and IAA had significant effects on banana dwarfing, while BR had little effect. The key gene in GA biosynthesis of is GA2ox, and the key genes in IAA biosynthesis are TDC and YUCCA. The differential expression of these genes might be the main factor affecting hormone levels and plant height. In terms of hormone signal transduction, DELLA and AUX/IAA repressor proteins were the core regulators of GA and IAA, respectively. They inhibited the process of signal transduction and had feedback regulation on hormone levels. Finally, the transporter protein PIN, AUX1/LAX protein family and ABCB subfamily played supplementary roles in the transport of IAA. These results provide new insights into GA and IAA regulation of banana growth and a reliable foundation for the improvement of dwarf varieties.
