ABSTRACT. Identity is a cohesive device that helps to have a better understanding of speech. This article analyzes the identity device and its sub-sets in some Persian live sport radio and TV programs. The theoretical framework of this research is Dooley and Levinsohn (2001). A data-driven approach based on the access to the detailed discourse context was used to have a reliable sample for the research. So, around 200 minutes of 20 different live sport radio and TV programs were transcribed. The authors present the identity extent of functionality via comparing its degree of frequency employing the SPSS software while evaluating the meaningfulness of differences in application of each of its sub-categories. This evidenceoriented research supports that the subcategories of identity can also be studied in Persian in the same way as Dooley and Levinsohn's (2001) view among which pronouns receive the most frequency whereas proforms do the least. Pronouns and ellipsis contain a meaningful difference between their application in radio and TV data. In addition, there is not any significant difference between the applications of repetition, substitution and other pro-forms. Finally, identity is reported as having a significant relation in its application in the research corpora.Keywords: identity, pronouns, pro-forms, ellipsis, substitution, repetition.Identidade: um recurso de coesão em falas de esporte ao vivo em rádios e TVs do Irã RESUMO. A identidade é um recurso coesivo que colabora com uma melhor compreensão da fala. Este artigo analisa o recurso da identidade e seus subconjuntos em programas esportivos, ao vivo, de rádio e TV em persa. O quadro teórico desta pesquisa é Dooley e Levinsohn (2001). Uma abordagem dirigida por dados baseada no acesso ao contexto discursivo detalhado foi utilizada para se obter uma amostra confiável para a pesquisa. Assim, em torno de 200 minutos de 20 diferentes programas ao vivo de esportes de rádio e TV foram transcritos. Os autores apresentam o alcance da identidade da funcionalidade pela comparação de seu grau de frequência empregando o software SPSS enquanto avaliam a significância das diferenças em aplicação de cada uma de suas subcategorias. Esta pesquisa orientada para as evidências sustenta que as subcategorias da identidade também podem ser estudadas em persa, de acordo com as propostas de Dooley e Levinsohn (2001), dentre as quais pronomes recebem a frequência mais alta, ao passo que pró-formas recebem as frequências mais baixas. Pronomes e elipse apresentam diferença significativa entre suas aplicações aos dados do rádio e da TV. Ademais, não há diferença significativa entre as aplicações de repetição, substituição e outras pró-formas. Finalmente, relata-se que a identidade apresenta relação significativa em sua aplicação na pesquisa.

This study focusing on physician-patient interactions aimed to find out whether physicians' gender and experience influence Persian doctor-patient interactions. So power strategies in physician-patient interactions were extracted and categorized to explore the relationship between physicians' gender and experience and power strategies. Fieldwork was conducted in clinics and hospitals of Rafsanjan city in Iran. One hundred physician-patient consultations were audiotaped and transcribed during 2011-2012. Woods' (2006) view was used to examine four strategies of power and knowledge on their talk. The findings pointed out the importance of investigating discourse of medicine in order to improve medical consultations, especially physician-patient interactions. Our study confirmed some previous assertions that physician-patient interactions were asymmetrical. Physicians controlled and dominated the medical consultations by questioning, interruptions, directive statements and tag questions. The analysis of the data revealed that all power strategies were applied in Iranian physician-patient interactions. The results of Chi-Square tests indicated that there was a significant relationship between power strategies and physicians' experience and gender. It was concluded that the female and inexperienced physicians tended to control consultations by questioning, interruption, directives and tag questions more than the male and experienced physicians.
