The authors propose an informed search greedy approach that efficiently identifies the influencer nodes in the social Internet of Things with the ability to provide legitimate ***,the proposed approach minimizes the network size and eliminates undesirable *** that,the proposed approach ranks each of the nodes and prioritizes them to identify an authentic ***,the proposed approach discards the nodes having a rank(α)lesser than 0.5 to reduce the network complexity.αis the variable value represents the rank of each node that varies between 0 to *** with the higher value ofαgets the higher priority and vice *** threshold valueα=0.5 defined by the authors with respect to their network pruning requirements that can be vary with respect to other research ***,the algorithm in the proposed approach traverses the trimmed network to identify the authentic node to obtain the desired *** performance of the proposed method is evaluated in terms of time complexity and accuracy by executing the algorithm on both the original and pruned *** results show that the approach identifies authentic influencers on a resultant network in significantly less time than in the original ***,the accuracy of the proposed approach in identifying the influencer node is significantly higher than that of the original ***,the comparison of the proposed approach with the existing approaches demonstrates its efficiency in terms of time consumption and network traversal through the minimum number of hops.

AIM To understand the experience of maternal depression, the factors implicated in accessing health, and the acceptability of the psychosocial intervention. METHODS The participants were recruited from the paediatrics outpatient department of Civil Hospital Karachi, Pakistan. The study started in December 2009 and completed in December 2010. Women with maternal depression, aged 18-44 years with children aged 0-30 mo who had received nutritional supplements, and participated in the intervention programme [called Learning through Play(LTP) plus] were included in the study. Qualitative interviews were conducted with 8 participants before the intervention and 7 participants after the intervention. A semi structured topic guide was used to conduct the *** Framework analysis procedures were used to analyse the qualitative data. Four themes emerged:(1) the women's contextual environment: Interpersonal conflicts, lack of social support and financial issues being the major barriers in assessing healthcare;(2) women's isolation and powerlessness within the environment: Sense of loneliness was identified as a restricting factor to access healthcare;(3) the impact of the intervention(LTP-Plus): Women felt "listened to" and seemed empowered; and(4) empowered transformed women within the same contextual environment: The facilitator provided a "gardening role" in nurturing the women resulting in a positive transformation within the same environment. The women's homes seemed to be more happy homes and there was a positive change in their behaviour towards their *** Findings informed the further development and testing of culturally-appropriate psychosocial intervention(LTP^+) for addressing maternal depression.
