SMI-SBC: Manipulated SMI-SBC
No full textThis study aims at examining the effect of consumers' perceived self-brand connection with an SMI (Social Media Influencer) on their willingness to pay for a product promoted by the SMI versus the brand
Comparison of adaptive radar algorithms : transformed SMI, eigencanceler, and SMI
No full textAdvanced airborne radars must perform target detection in the presence of interference and heavy clutter. In many applications, the practical usefulness of adaptive arrays is limited by their convergence rate. In this paper, we first analyze the performance of the SMI method. Then, two other methods, the transformed SMI and the eigencanceler, both based on the principle component inversion (PCI) technique, are described and analyzed by simulation. It is shown by simulation based comparison that the transformed SMI and the Eigencanceler outperform the SMI method. It is also shown that the transformed SMI and the eigencanceler has higher convergence rate in terms of output signal-to-noise ratio than the SMI, specially for short data record sizes. It is concluded that the transformed SMI and the eigencanceler are good alternatives to the SMI method when data set available is small
The influence of social media influencer (SMI) and social influence on purchase intention among young consumers
No full textThe implications of social media influencers (SMI) are more important than ever, specifically
considering online purchasing has become a trend, more so as a result of the COVID-19 pandemic.
In this respect, brands must employ social media influencers to attract customers, and who needs
be more creative than traditional advertisers in generating purchase intent. In this context, our study
employed the TEARS model (i.e. trustworthiness, expertise, attractiveness, respect, similarity) and
the social influence theory to understand the predictors of consumer purchase intention. Our study
aimed to examine: (1) the characteristics of social media influencers (i.e. trustworthiness, expertise,
attractiveness, respect, similarity) as predictors of intention to purchase, and (2) the relationship
between social influence and purchase intention among Gen Z. A total of 605 useable responses
were collected. The study findings suggest that the four dimensions of the TEARS Model were
established as predictors for purchase intention among Gen Z consumers with the exception of
“Respect”. Besides, informational and normative influence were significant predictors of purchase
intention. The study adds to the growing body on SMI impact by revealing the elements that influence
Gen Z’s purchase intention. Our findings also shed further light on the understanding of the social
influence theory and TEARS Model in a collectivist culture, particularly in the SMI context

SMI SBC Similarity Pretest
No full textThis pretest aims to test the effectiveness of a manipulation to lower SMI similarity and to assess whether similarity moderates the effect of SBC on social comparisons with the SMI

Effectiveness of psychological interventions for carers of patients with severe mental illness (SMI): a systematic review
No full textObjectives
Interventions for carers of patients with severe mental illness (SMI) are effective in improving patient outcomes. This review examined the effectiveness of psychological interventions or support designed to help carers of patients with SMI.
Design
A systematic review of randomised controlled trials (RCTs) was conducted. Study selection, data abstraction and risk of bias assessments were independently conducted and duplicated. The reporting of this review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
Data sources
CINAHL, CENTRAL, EMBASE, Medline and PsycINFO were searched from inception to 30 April 2024.
Eligibility criteria
Only studies using an RCT were considered. All other research designs were excluded. The included population was carers over 18 caring for a patient with SMI. Any psychological, psychosocial or psychoeducational interventions were included. Patients under 18, diagnosed with dementia or learning disabilities comorbidity, were excluded.
Data extraction and synthesis
Study characteristics and outcome data (mean and SD) for each included study were collected. Review Manager (RevMan) was used to manage the data. Meta-analysis was not considered appropriate due to the heterogeneity of the included studies. The results were presented as a narrative synthesis.
Results
This review included 3869 participants from 32 RCTs and demonstrated a beneficial effect of psychological interventions for carers. Psychoeducation was widely used and the most evaluated intervention for carers.
Conclusions
Psychological interventions for carers are beneficial in helping to reduce negative outcomes and enhance positive outcomes. Future research could focus on exploring the impact of interventions on less evaluated outcomes such as depressive and anxiety symptoms
