This study aims to investigate the impact of the source of the content in social media communication and the content distribution intensity on consumer-based brand equity (CBBE) dimensions and how the study will eventually impact purchase intention.

A total of 521 samples were collected using an online survey questionnaire. The respondents' validity was verified using purposive sampling techniques, and the responses were analysed using SmartPLS 3.0.

The authors outlined the fundamental mechanisms of what makes social media communication effective and discovered that emotional-based brand equity dimensions (brand association and brand loyalty) remained significant in influencing purchase intention. However, attribution-based brand equity dimensions (perceived quality, brand trust and brand awareness) are found to have no impact.

This study decomposed social media communication into three different dimensions, and the authors' result showed that the dimensions do not impact CBBE to the same extent. The authors concluded that some CBBE dimensions, which appear to be a rigour determinant of purchase intention over time, have a feeble effect during the pandemic. The existing relationship between the CBBE dimensions with purchase intention might not hold in the pandemic context. The authors suggested that anxiety or pandemic fear could alter the normal consumer buying process and make some well-established relationships not hold. As research indicates that pandemics are reoccurring events, the authors' study contributes to the global effort to dampen some of the pandemic-related effects on business and marketing.

Unauthorised file sharing (UFS) in online communities (OCs) is a major intellectual property concern. Researchers have traditionally viewed UFS as digital piracy and have suggested that deterrents, such as legal actions, should be in place. However, previous research has not considered the OC context and cannot explain why OC members share unauthorised files even when there is legislation against this in place. In OCs, UFS exhibits features of public goods contribution. Therefore, the authors claim that public goods contribution motivations can provide a compelling explanation for UFS in OCs.

The authors propose a theoretical model in which two egoistic public goods contribution motivations (namely, warm-glow giving and demand for resources) are tested alongside motivations informed by the sanctions described by deterrence theory, a theory widely used within the digital piracy perspective.

The authors find that warm glow and demand for resources are positively related to UFS in OCs; the effect of warm glow is moderated by users' attachment to OCs. Importantly, the results suggest that although sanctions significantly predict UFS, the effect of sanctions on UFS becomes insignificant in the presence of warm glow, demand for resources and attachment.

The study offers new insights into why users engage in UFS and highlights that public goods contribution should be taken into account in developing anti-piracy policies and practices.

This study aims to determine the prevalence and predictors of postpartum depression (PPD) among nursing mothers in Nsukka, Nigeria.

This study was a descriptive cross-sectional survey among nursing mothers in three hospitals in Nsukka, Nigeria. Data was collected using a self-administered Edinburgh Postpartum Depression Scale (EPDS) and sociodemographic form. The data obtained were analyzed using descriptive statistics, chi-square test and binary logistic regression.

A total of 270 nursing mothers participated in this survey, giving a response rate of 94.4%. The prevalence of PPD among the study group was 20.0%. However, women who did not have complications during childbirth were about two times (AOR = 0.417, 95% CI = 0.204, 0.852, P = 0.016) less likely to develop symptoms of PPD than women who experienced birth complications. In addition, women who had poor relationships with their partners have approximately seven times (AOR = 6.994, 95% CI = 1.110, 44.059, P = 0.038) higher odds of developing PPD compared with those women who had excellent relationships with their partners.

The sample size was small, hence, might limit the generalizability of its findings beyond the study group. Health-care practitioners should provide appropriate interventions to women at a higher risk of developing PPD on the need to maintain a healthy and supportive relationship with their partners.

This study provides unique insight into PPD among nursing mothers and its determinants from a different regional, socioeconomic, societal expectations, social support system, access to health care and cultural context.
