Using two quantitative methods, this study sought to understand whether user-generated posts would vary in frequency of incivility, impoliteness, and deliberative attributes on Twitter versus Facebook. A quantitative content analysis ( N = 1458) revealed that posts responding to the White House’s tweets were significantly more uncivil and impolite and less deliberative than responses to White House Facebook posts. Also, comments on posts that concerned sensitive topics (such as same-sex marriage) were more uncivil, impolite, and deliberative than comments regarding less sensitive topics (such as technology). An experiment ( N = 198) showed that people were more deliberative when responding to White House Facebook posts, compared with White House tweets, but no differences were found for incivility and impoliteness. Results suggest that both the varying affordances of the two platforms and the fact that the two sites may attract different types of people might explain these results.

Purpose – The aim of this study is to determine social media use by consumers for travel-related purposes. Design/methodology/approach – A quantitative study was conducted after reviewing the related literature. The primary data were collected by means of an online questionnaire, and the results were analyzed using a statistical package program. Findings – The respondents use social media intensively both in their daily lives ( > 96 per cent) and in travel-related activities (95 per cent). In addition to the detailed analyses of their usage, a model was developed to identify the factors behind social media use for travel-related purposes. Research limitations/implications – As a result of an online questionnaire method, only consumers having an Internet access could respond to the survey. Additionally, the sample was not random, and the respondents were selected only from Turkey. Consequently, the study may suffer from a generalization problem, especially for markets with major different cultural characteristics. Practical implications – The findings of the study may assist academics and practitioners to better understand social media and Web 2.0 technologies and their effects on consumers. Originality/value – One of the dominant trends affecting consumer behavior and tourism marketing in recent years is the use of social media. It is critical to understand such developments and their effects on consumer behavior that may impact on the distribution and accessibility of travel-related information.

This article seeks to analyse how different sets of media covered the Gezi protests, whether the protest paradigm model varied according to the ideological leanings of newspapers, and whether social media created an alternative way for citizens to gather information while bypassing domestic news media. Furthermore, the study examines protesters' perceptions of mainstream media coverage of the Gezi Park protests. It is important to understand how the exchange of information and idea flows in a polarized media environment and social media tools affected this process in Turkey.

A 50-year-old man, transferred from another hospital, was admitted because of adult onset seizures. Nine months earlier, he had undergone an esophagogastrectomy; the lesion was confirmed to be a carcinoid tumor. Laboratory tests, chest x-rays, and electrocardiogram were normal. A second liver and spleen scan was performed. A computed tomographic scan revealed a well-circumscribed homogeneous enhancement of a lesion in the left frontal superficial area. On the 10th day, the patient underwent a left frontal parietal craniotomy. Postoperatively, he manifested no residual neurological deficits and was discharged on the 6th postoperative day. A week later, he was readmitted for treatment of aphasia and right hemiparesis; he was treated and discharged. The patient survived 16 more months. The occurrence of central nervous system metastasis from carcinoid tumor is rare. This tumor resembled, in many respects, a parasagittal meningioma. Radiological findings on the computed tomographic scan were typical of these tumors. This patient was diagnosed as having metastatic disease just 9 months after the diagnosis of the primary tumor and 13 months from the onset of any symptoms. This is a short period of time compared with that reported in other cases.
