A Systematic Literature Review of the Intersection between Social Media and Cultural Identity: Implications for Agricultural and Environmental Communication

Social media has radically changed human communication patterns, impacting how people perceive scientific information. This study sought to explore how cultural identity impacts the use of, and engagement with, social media content related to agriculture and the environment. Informed by Social Representation Theory, a systematic qualitative literature review was conducted to investigate how cultural identity impacted engagement with social media sources of agricultural and environmental information. Several studies indicated differences in social media engagement between people from different cultures. However, different definitions and perspectives on cultural identity emerged with some researchers describing culture in relation to nationality and others in terms of beliefs. In cases where culture was described in relation to beliefs, it was observed that individuals are more likely to defend beliefs central to their sense of identity when contradicted by new information. Despite the availability of several studies integrating cultural identity, environment, and social media, a gap was observed within research explicating directly the intersection between science communication, cultural identity, and social media. Additionally, differences emerged between research on social media and cultural identity within agricultural communication as compared with more general environmental communication. Due to the changing dynamics in agricultural and environmental communication proliferated through social media, scholars should place greater emphasis on research aimed at investigating the impact of social identity, social media, interaction and engagement with online communication messages. Future research should investigate how a holistic social identity impacts individuals’ perceptions of science communication messages, as no clear answer emerged within the current literature

Lived Experiences during International Service Learning: A Semiotic Analysis of Photo Journals

International service learning (ISL) is a pedagogical approach used to prepare students to be global citizens and has emerged as a popular short-term program model for international experiences. Few studies of ISL have integrated semiotic photo analysis into their evaluations. Combining students’ photographs with text encourages reflection on knowledge and experiences as well as how they are related. The current study used semiotic analysis to understand the lived experiences of students on an ISL to Guatemala. The participatory nature of the research process was critical to the semiotic analysis, as the researchers had an understanding of the cultural perspectives and traditions that emerged in the images which could have been overlooked by a researcher without knowledge of the specific cultural context. Participants kept a photo journal of 10 images and associated narratives to depict their experiences on the ISL. Both semiotic and content analysis were conducted on each journal entry. Coding yielded nine themes: new perspectives, personal connections, impact of coffee, intercultural comparisons, reality of life in Guatemala, cultural values, impact of ISL, connection to photograph, and sense of place. Combining the semiotic and content analysis yielded concurrent meanings through narrative and visual reflections, which, when combined with the researchers’ participatory knowledge of the experience, informed future ISL projects for the research and teaching team. The combination of visual and narrative methods required students to think about what story they will tell about their experience, and brings new layers of meaning to the reflection process

Development and Validation of the International Extension Network Advocacy Capacity Scale

Extension is sometimes viewed globally as less important than academic research and innovation, even though these networks are crucial to agricultural development. Using Lewin’s (1947) organizational change theory as a conceptual background, an instrument to measure advocacy capacity within international extension networks was developed. The resulting scale was analyzed for content validity, response process validity, internal structure validity, and consequential validity. An exploratory factor analysis (EFA) was performed on the proposed scale. The underlying structure of the scale was found to load onto five factors. The five extracted factors were labelled: 1) network support of advocacy, 2) network integration of advocacy, 3) network influence in advocacy, 4) network visibility in advocacy, and 5) network advocacy performance. The overall International Extension Network Advocacy Capacity (IENAC) scale, and associated subscales were all found to have acceptable levels of validity

Knowledge translation strategies to improve the use of evidence in public health decision making in local government: intervention design and implementation plan

Background:&nbsp;Knowledge translation strategies are an approach to increase the use of evidence within policy and practice decision-making contexts. In clinical and health service contexts, knowledge translation strategies have focused on individual behavior change, however the multi-system context of public health requires a multi-level, multi-strategy approach. This paper describes the design of and implementation plan for a knowledge translation intervention for public health decision making in local government. Methods: Four preliminary research studies contributed findings to the design of the intervention: a systematic review of knowledge translation intervention effectiveness research, a scoping study of knowledge translation perspectives and relevant theory literature, a survey of the local government public health workforce, and a study of the use of evidence-informed decision-making for public health in local government. A logic model was then developed to represent the putative pathways between intervention inputs, processes, and outcomes operating between individual-, organizational-, and system-level strategies. This formed the basis of the intervention plan. Results: The systematic and scoping reviews identified that effective and promising strategies to increase access to research evidence require an integrated intervention of skill development, access to a knowledge broker, resources and tools for evidence-informed decision making, and networking for information sharing. Interviews and survey analysis suggested that the intervention needs to operate at individual and organizational levels, comprising workforce development, access to evidence, and regular contact with a knowledge broker to increase access to intervention evidence; develop skills in appraisal and integration of evidence; strengthen networks; and explore organizational factors to build organizational cultures receptive to embedding evidence in practice. The logic model incorporated these inputs and strategies with a set of outcomes to measure the intervention\u27s effectiveness based on the theoretical frameworks, evaluation studies, and decision-maker experiences. Conclusion: Documenting the design of and implementation plan for this knowledge translation intervention provides a transparent, theoretical, and practical approach to a complex intervention. It provides significant insights into how practitioners might engage with evidence in public health decision making. While this intervention model was designed for the local government context, it is likely to be applicable and generalizable across sectors and settings.</div

Phenome-wide association analysis of LDL-cholesterol lowering genetic variants in PCSK9

Abstract: Background: We characterised the phenotypic consequence of genetic variation at the PCSK9 locus and compared findings with recent trials of pharmacological inhibitors of PCSK9. Methods: Published and individual participant level data (300,000+ participants) were combined to construct a weighted PCSK9 gene-centric score (GS). Seventeen randomized placebo controlled PCSK9 inhibitor trials were included, providing data on 79,578 participants. Results were scaled to a one mmol/L lower LDL-C concentration. Results: The PCSK9 GS (comprising 4 SNPs) associations with plasma lipid and apolipoprotein levels were consistent in direction with treatment effects. The GS odds ratio (OR) for myocardial infarction (MI) was 0.53 (95% CI 0.42; 0.68), compared to a PCSK9 inhibitor effect of 0.90 (95% CI 0.86; 0.93). For ischemic stroke ORs were 0.84 (95% CI 0.57; 1.22) for the GS, compared to 0.85 (95% CI 0.78; 0.93) in the drug trials. ORs with type 2 diabetes mellitus (T2DM) were 1.29 (95% CI 1.11; 1.50) for the GS, as compared to 1.00 (95% CI 0.96; 1.04) for incident T2DM in PCSK9 inhibitor trials. No genetic associations were observed for cancer, heart failure, atrial fibrillation, chronic obstructive pulmonary disease, or Alzheimer’s disease – outcomes for which large-scale trial data were unavailable. Conclusions: Genetic variation at the PCSK9 locus recapitulates the effects of therapeutic inhibition of PCSK9 on major blood lipid fractions and MI. While indicating an increased risk of T2DM, no other possible safety concerns were shown; although precision was moderate

The development and validation of a scoring tool to predict the operative duration of elective laparoscopic cholecystectomy

Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p  90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care

Using Participatory Rural Appraisal for a Community Needs Assessment in Timor-Leste

Conducting timelyand effective needs assessments in the field is important for international development work. In many cases, a researcher has only a couple of hours to build rapport with a community, visually examine the state of the field, and conduct the needs assessment and achieve open, honest, and valid data. Working with translators further constrains the process by cutting available time. Thus, research focused on conducting these types of international assessments is valuable. This study aimed to identify the key needs of theFatubesi community in Timor-Leste using a combination of techniques for Participatory Rural Appraisal (PRA)—a transect walk and a small group discussion that included guided questions and ranking priorities. PRA is context specific and emphasizes facilitation of co-learning between local knowledge and outside expertise (Toness, 2005). Water, new fencing, and technical training/seeds were identified as the top three priorities for the community and their gardens, and the transect walk revealed issues with infrastructure that provided visual context for the small group discussion. The results of this study reflect the unique challenges faced by many communities in international development settings. The techniques described in this article are beneficial when used together for PRAto shift roles from expert facilitator to local empowerment
