- Anorexia nervosa versus bulimia nervosa: differences based on retrospective correlates in a case-control studyPublication . Machado, Bárbara César; Gonçalves, Sónia F.; Martins, Carla; Brandão, Isabel; Roma-Torres, António; Hoek, Hans W.; Machado, Paulo P.Objective This study is the result of two Portuguese case– control studies that examined the replication of retrospective correlates and preceding life events in anorexia nervosa (AN) and bulimia nervosa (BN) development. This study aims to identify retrospective correlates that distinguish AN and BN Method A case–control design was used to compare a group of women who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for AN (N = 98) and BN (N = 79) with healthy controls (N = 86) and with other psychiatric disorders (N = 68). Each control group was matched with AN patients regarding age and parental social categories. Risk factors were assessed by interviewing each person with the Oxford Risk Factor Interview. Results Compared to AN, women with BN reported significantly higher rates of paternal high expectations, excessive family importance placed on fitness/keeping in shape, and negative consequences due to adolescent overweight and adolescent objective overweight. Discussion Overweight during adolescence emerged as the most relevant retrospective correlate in the distinction between BN and AN participants. Family expectations and the importance placed on keeping in shape were also significant retrospective correlates in the BN group.

- Brand logo and brand gender: examining the effects of natural logo designs and color on brand gender perceptions and affectPublication . Machado, Joana César; Fonseca, Beatriz; Martins, CarlaThis paper examines how a critical dimension of logo design, namely naturalness, along with logo color, influences brand gender perceptions, and whether brand-design-induced gender perceptions ultimately impact affective reactions to logos. Data were collected from a sample of 260 participants, using a set of 24 unknown, manipulated logos as stimuli. Results suggest that while cultural logo designs effectively convey brand masculinity, organic logo designs enhance femininity perceptions. Using dark blue and light pink logo colors reinforce masculinity and femininity perceptions, respectively. Both logo masculinity and logo femininity have a positive effect on the affective response toward logos. Furthermore, this research analyzed the moderation effect of color on the link between logo design and logo gender perceptions, as well as the moderation effect of consumers’ gender in the link between logo gender perceptions and affect toward the logo. However, none of these moderation effects were supported by the data. This is the first research to empirically test the effect of natural logo designs on brand gender perceptions and, thereby, on affective reactions toward the logo. The findings provide practical guidelines about the design of a gendered logo using the naturalness of logo design and logo color, thereby facilitating gender targeting efforts
- Cause-related marketing in online environment: the role of brand-cause fit, perceived value, and trustPublication . Silva, Susana Costa e; Duarte, Paulo; Machado, Joana César; Martins, CarlaThis article explores how cause-related marketing influences consumer response in an online environment, by analyzing the relationships between consumers’ perceptions of Cause-related Marketing (CrM) and their behavioral intentions toward an online store. Data was collected through an experiment using a sample of Portuguese respondents focusing on the effects of the cause–brand fit and consumer–cause identification on online stores perception and purchase intention. Structural equation modeling was used to analyze the data. The results show that consumer–cause identification has a positive impact on perceived value and that the relationship is moderated by brand–cause fit but it does not influence online purchase intention. Brand–cause fit was shown to have a positive influence on trust and online purchase intention, which is also impacted by perceived value. Trust was found to be a predictor of perceived value but not of the online purchase intention. The main contributions of the findings include the improved understanding of the importance of the fit to consumer’s perception and efficacy for online cause-related marketing campaigns.
- Company social networks: customer communities or supplementary services?Publication . Martins, Carla; Patricio, LiaPurpose: The purpose of this study is to contribute to a better understanding of the antecedents and consequences of loyalty to consumer networks hosted by companies in the scope of social networking sites (SNS). These company social networks (CSNs) have traditionally been studied as online brand communities but more research is needed to understand their role for host companies. Design/methodology/approach: This study identifies CSN performance dimensions (host reputation, informativeness, communication self-expressiveness, rewarding activity and consumption support) and analyzes how they influence attitudes and behavioral intentions toward CSNs (identification with the community, satisfaction and loyalty) and toward the host company (satisfaction and loyalty). A conceptual model is tested through a survey administered to members of a large grocery retailer CSN on Facebook. Findings: Results show that all six identified performance dimensions significantly impact CSN loyalty. However, while self-expressiveness, communication and rewarding activity (which are closely related to social and hedonic value) are predictors of loyalty to the CSN, through the mediation of identification with the community, they neither indirectly (through the mediation of identification) nor directly impact satisfaction with the host. Conversely, informativeness, communication and host reputation are good predictors of loyalty to the CSN, through mediation of satisfaction with the CSN, and also exert an indirect positive influence on satisfaction with the host. Finally, consumption support positively influences loyalty to the CSN through the mediation of identification with the community and directly positively influences satisfaction with the host company. Originality/value: These results reveal the dichotomous nature of CSNs, as communities of people with shared interests and supplementary services created by companies to add value to their core offering. While perceptions regarding the community facet are independent from attitude toward the host, perceptions regarding supplementary service are significant predictors of satisfaction with the host. These results offer implications for future research and management of companies’ social media presence.
