Purpose: The popularity of social networks has created business opportunities to the electronic commerce environment, being recently named as social commerce. The purpose of this paper is to analyze – from the perspective of the consumer – the main factors and characteristics (personal or related to the products bought) that have influenced consumers to participate in social commerce buying, recommending, comparing and sharing information about products and services in online marketplace and communities. Design/methodology/approach: The study is characterized as an exploratory descriptive research, operationalized through a survey, applied to 229 participants of the social network Facebook. The research involves a qualitative stage for identifying potential variables that influence the participation of consumers in social commerce, followed by a quantitative one, including data collection procedures, validation and data analysis. Findings: The results show trust, perceived usefulness and information quality as the factors that most influence consumer participation in social commerce, being trust in the website the main predictor. Concerning the characteristics, the findings also show that more expensive products and products classified as computers and electronics use ratings, recommendations and comments online more intensively than books, travel, household appliances and fashion products. Research limitations/implications: As limitations of the study, the authors highlight the small number of interviews conducted during the qualitative stage, which may have left out other relevant factors of the analysis on consumers’ participation in social commerce. Another limitation refers to the selection of the participants of the study; all members of the social network Facebook are identified by the contact net of the authors – though it has been tried to enlarge this contact list by requesting the respondents to share the questionnaire link with their acquaintances, we should be cautious about the generalization of the results. Originality/value: The study proposes an instrument to identify factors and characteristics that are taken into consideration by the consumers when participating in social commerce. Such a tool can be replicated by firms included in this type of commerce, in order to evaluate the behavior and perception of their customers about their performance in the online environment. This study also highlights trust, information quality and perceived usefulness of the website as the most influencing factors of the consumers’ participation in social commerce. In addition, the authors identified that more expensive products and products classified as computers and electronics seem to use more intensively ratings, recommendations and comments online provided by other people. This fact supports the research literature that (positive or negative) online recommendations influence the consumers purchase behavior, reducing uncertainties about the products and increasing credibility and trust.

The evolution of Web 2.0 technologies and social media has changed the way online business is conducted. With increasingly popular social networks, the connections among Internet users emerge as an important source of information, allowing consumers to share their ideas, opinions, or even content on the web, in order to find better and cheaper products, originating a new type of electronic commerce, known as social commerce (s-commerce). In this context, price and trust stand out as two important factors influencing the decision to buy online. Thus, we aimed to analyze the effects of trust and competitive price on the purchase intention of Brazilian consumers in s-commerce. Through a survey conducted with 160 online consumers, we identified trust as the main predictor of consumer purchase intention in s-commerce followed by competitive prices. We also indicated a set of important antecedents of trust in the context of s-commerce. The study contributes to the literature surrounding the effects of competitive price and trust - and its antecedents - as important factors that influence the intention to buy in s-commerce, providing managers with some key elements they can use to improve their firm’s competitiveness in this new business environment.

Constantly experiencing limiting situations that hinder a professional practice coherent with its principles - of autonomy and advocacy of users' interests -, and often conditioned to experience moral distress, the nursing profession plays a prominent role in the current health model because it has the characteristic of managing the care rendered to users in a perspective of social inclusion, both in the basic health network and in hospitals. Aiming at carrying out a reflection on the nursing practice and the difficulties present in its work routine, and considering its characteristics as a profession, this article sought to make a reflection between the practice of nursing and the numerous moral challenges imposed by the routine, resulting, in many cases, in a value crisis that can reverberate directly on the quality of the service rendered, and in abandonment of the ideals of advocacy for users.

The Moral Distress Scale was designed to assess the severity and frequency of the moral distress experienced by nursing professionals in everyday situations. The objective of this study was to analyze the psychometric characteristics of the Moral Distress Scale adapted to Brazilian nursing. Through factor analysis, five constructs were identified: lack of competence in the work team; disregard for patient autonomy, inadequate working conditions, denial of the nursing role as an advocate in terminal patients; denial of the nursing role as an advocate of the patient. The proposed pentafactorial solution is statistically and semantically more appropriate to the Brazilian nursing scenario. Based on these results, the scale is considered to be valid and reliable, showing the necessary requirements regarding convergent and discriminating validity as well as internal consistency to be used while evaluating the intensity and frequency of moral distress in Brazilian nursing professionals.
